Ok so everyone has one PSU right? Why not run 2 PSU's? have one for the mainboard and peripherals, and second strictly for video, can't you just plug it in the wall and only connect the PSU to the cards alone?

Im thinking about trying it but dont want to melt anything, plus im too lazy to do the math...

Just thought of it cuz i was shoppingfor a psu and noticed there isnt many on the market that have more than 4 pcie 6+2 pins or 8 pin pci connections, an yo cant split one connection, so how am i to supply 4 5850's with 180 watts each? any ideas?

Thought of that, sounds like ill be sticking with that too, but I would love to try 2 PSU's, 2 modular 600 watt should do the trick as long as they have atleast 4x6 pin connectors each, shouldnt be too bad to setup, just need some solder and some cable ties

OR.... I could run a 750 and a 500 maybe

EDIT: my mainboard has a pci-e auxilliary power molex connection inbetween the obgpu and the pci-e x16 slots, still waiting to hear back from biostar to see what its rated for, I doubt it will help with any of the cards at all, im sure its only there fo the obgpu
